General rule of thumb is the 3 gram mark produces stimulation. The more you take the more likely it will become relaxing instead. I've found myself tweaked off of red vein leafs at the 3 gram mark even if that same bag would make me relaxed when taking 5 grams. If you're looking for energy try a white leaf version, take 3 grams (on an empty stomach) then wait an hour before taking another gram. Repeat until you find the desired effect.
White leaf strains never work well for me.
I don't really feel that 3 gram rule of thumb is true for me.
I mean I took a 10 month break but I hadn't been smart back then and was up to 16 gram doses about 4 days a week.
Now I'm not going to do that again and my tolerance has dropped dramatically but it's still quite difficult to figure out the right dose but I've had the most success in the past few days by dosing between 6-8 grams which is higher than what many people do but still no more than half of what I was once at so I feel ok with it as long as I never go above, say, 8.5 grams a dose.
The other day I went to 9.5 simply cause i had such little left in one bag I figured I'd finish it off and regretted it and started nodding off (some people like that but I don't) so I now know that anything above 8.5 is too much, but at 3 I think the high would still be too mild for me. When you have dosed as high as I did I think it's really difficult to ever get to the point where 3 gram doses produce a full effect, but I do still get a nice mild buzz off of that.
I'm not sure there's a standard dose for everyone that produces the same effects, but most certainly not in someone who was dosing as high as I had been.
Once you go that high, all bets are off LOL, and seems like now that I'm experimenting with it again my receptors are trying to figure out exactly what is going on and how to react to the doses at this point.
I'm telling myself firmly though that I can't do this for more than like 8 weeks, at maybe 2-3 days a week MAX.
For me getting too into it and using all the time led to some problems and I'm not going down that road again.
